Thanks Thomas.
Will update the following commit-log in patch v4
A meter policy with RSS/Queue action is not supported
when dv_xmeta_en enabled.
When dv_xmeta_en enabled in legacy creating flow,
it will split into two flows (one set_tag with jump flow and one RSS/queue =
action flow).
For meter policy as termination table, it cannot split flow and cannot supp=
ort
dv_xmeta_en enabled.
Regards,
Li Zhang

It is still not explaining why.

It is still not enclosed like this: ``dv_xmeta_en``
Don't you think "enabled" is better than "not zero"?
